Abstract:
The present consortium (“Petru Poni” Institute of Macromolecular Chemistry – PPIMC Iasi, Stefan cel Mare” University – USV, Suceava and APEL LASER SRL) aims to work together on a multidisciplinary joint project around a very hot topic regarding optoelectronics: white organic light emitting diodes (WOLED). In the context of the global warming, several governments took measures to promote better energy efficiency through advanced lighting technologies. Within this context, European Union set new energy efficient requirements for the lamps produced starting with September 2009, the traditional incandescent and halogen bulbs being gradually eliminated from the market. WOLED lamps are recommended as alternatives to the conventional incandescent bulbs. This is the reason why, in the last years, the thermally activated delayed fluorescence emitters consisting of strong donor-acceptor organic molecules have become highly attractive, in particular due to their applicability for low energy consuming electro-luminescent devices such as WOLEDs. The aim of this project is to obtain an OLED configuration able to be competitive on the Romanian market and not only. To achieve this target, WOLED configuration is thought according with the hottest researches within WOLEDs field and comprises original elements designed to improve the commercially WOLED performances. This includes combined efforts in chemistry, physics and engineering towards the obtaining of new materials, new device concepts, and new technological approaches and to a deeper understanding of the involved basic processes that are determining the devices performance, reliability and durability. The general aim is to reduce the cost, increase the performance and improve configurability, scalability, adaptability, reliability and self-adjusting capabilities of the integrated electronic, optoelectronic and photonic components. To realize a WOLED with increased performances, we propose the obtaining of a new hybrid material as emissive layer, being composed of two thermally activated delayed fluorescence compounds, e.g., green and red emitters, respectively, dispersed as nanometric droplets/nanocrystals into a fluorescent, blue emitting matrix. After varying the molar ratio between the three components, a white light emission will be achieved. To assure the best purity of the hybrid material components, the low molecular weight compounds will be obtained in form of single crystals, while the polymers will be synthesized through electropolymerization. The hybrid material and its components will be structurally confirmed and the film forming ability, electrochemical, optical, electro-optical, mechanical and morphological properties will be determined with the aim to choose the most appropriate material for WOLED configuration. The materials with optimal balance of properties, i.e., good flexibility, white emitting and good quantum efficiency will be selected, and a simulation of the WOLED configuration will be done based on their electrochemical characteristics (HOMO/LUMO levels, band gap, and reversibility of oxidation and reduction processes). The results of simulation process will allow us to choose an optimal configuration to determine the WOLED maximum performances. The electrodes and the substrate with the proper characteristics will be obtained in our laboratories, thus avoiding the eventually inadequacies caused by the use of commercial products. An original element of the proposed configuration is the creation of a new substrate with a refraction index close to air by dispersing liquid crystals in a polymer matrix.

Abstract:
THE PROJECT HAS AS MAIN OBJECTIVE THE FORMATION OF A YOUNG RESEARCH TEAM IN THE FIELD OF MATERIALS BASED ON AROMATIC POLYMERS WITH CONDENSED RINGS, SUBSCRIBING TO THE THEMATIC AREA S&T PRIORITY NO. 4
, ACCORDING TO PC7 OF EU. THE PRINCIPAL IDEA OF THE PROJECT IS THE DESIGN OF POLYMERS WITH A OPTIMUM COMBINATION OF ELECTRONODONOR AND ELECTRONOACCEPTOR AROMATIC RINGS IN THE SAME REPEATING UNIT OF THE POLYMER CHAIN, SO THAT AN EFFICIENT TRANSPORT OF CHARGE CARRIERS WILL BE ACHIEVED AS TO RENDER SIGNIFICANT ELECTRONIC AND OPTOELECTRONIC PROPERTIES FOR FUTURE USE IN NANOTECHNOLOGIES. FOR OUR PURPOSE, NEW POLYIMIDES AND POLY(AMIDE-IMIDE)S WITH CONDENSED RINGS AND FLEXIBLE GROUPS WILL BE SYNTHESIZED. THE POLYMERS WILL BE DESIGNED AS TO HAVE SATISFACTORY SOLUBILITY AND PROCESSABILITY, THERMAL, PHYSICO-MECHANICAL, OPTICAL AND ELECTRICAL PROPERTIES SUPERIOR TO THOSE OF CONVENTIONAL POLYMERS. THE POLYMERS WILL BE PREPARED BY VARIOUS TECHNIQUES BASED ON POLYONDENSATION REACTION OF AROMATIC MONOMERS THAT WILL BE EARLIER SYNTHESIZED: OXADIAZOLE-CONTAINING DIAMINES, DIACID CHLORIDES, DIANHYDRIDES ETC. THE DETAILED PROCESSES FOR THE MONOMERS AND POLYMERS SYNTHESIS WILL BE APPOINTED. ALL THE MONOMERS AND POLYMERS WILL BE STRUCTURALLY CHARACTERIZED BY SPECTRAL METHODS OR ELEMENTAL ANALYSIS. THE POLYMERS PROCESSABILITY INTO THIN FILMS AND COATINGS WILL BE TESTED AND A DETAILED STUDY OF THE CRISTALINITY, THERMAL STABILITY, GLASS TRANSITION, ELECTRICAL, MECHANICAL, LIQUID CRYSTALLINE, PHOTO- AND ELECTRO-OPTICAL PROPERTIES OF THE POLYMERS WILL BE PERFORMED, AS WELL. THE FILMS WILL BE STUDIED BY ATOMIC FORCE MICROSCOPY, DYNAMO-MECHANICAL ANALYSIS, DIELECTRIC SPECTROSCOPY ETC. THOSE POLYMERS HAVING AN OPTIMUM COMBINATION OF PROPERTIES AND GOOD PROCESSABILITY WILL BE SELECTED FOR TESTING IN ELECTRONIC DEVICES, SUCH AS OLEDS AND OFETS.
